running octave-0.79 on a sun3/160 under SUNOS4.1.1,
compiled with f2c and gcc-2.4.5

I applied your patches from Wed, 10 Nov 93 15:09:04 CST


-------------------------------------------------------------
Bug1:

I have two octave files containing:

fileA.m:

	     a=1;

	     function y=f(x)
		   y=10*x;
	     endfunction

	     b=2;

fileB.m

	     function y=f(x)
		   y=10*x;
	     endfunction

	     a=1;
	     b=2;

only fileA will run under octave:

octave:1> fileA

warning: ignoring trailing garbage after end of function
         near line 3 of file `fileB.m'
warning: function name `f' does not agree with M-file name `fileB.m'
error: `fileB' undefined near line 2 column 1
error: evaluating expression near line 2, column 1
octave:3> 


-------------------------------------------------------------------
Bug2:

  octave will exit with SIGSEGV in function qzval

octave:1> a=[1,3;7,8]
a =

  1  3
  7  8

octave:2>  b=[1,1;2,2]
b =

  1  1
  2  2

octave:3> qzval(a,b)
error: caught SIGSEGV -- stopping myself...

  Running the same script on a DEC ULTRIX V4.3 (Rev. 44) 
  with octave compiled with gcc-2.5.4 
  did not cause any problems.

  Running octave under gdb indicated that the problem on the sun3-160 occurs in 
  g++include/Complex.h.

  Because I was using an 'old' gcc version 2.4.5 I decided to install the
  latest version 2.5.6

  Trying to recompile octave with gcc-2.5.6 ended up with:
